HOISTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 462,438, dated November 3, 1891.

Application filed November 29, 1890. Serial No. 373,052. (No model.)

T0 aZZ witam it may concern:

Be it known that I, SAMUEL KAYE, a citizen of the United States, residing at Yazoo City, in the county of Yazoo and State of Mississippi,V have invented certain new and useful Improvements in IIoisting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a hoisting apparatus, and particularly to apparatus for hoisting ice, its object being to produce a device that will displace the usual endless chain used for such purpose and will be efiicient and serviceable, and in which, while the whole is hung by a single swiveled hook, yet the windlass Will be held in convenient position for manipulation.

To these ends my in vention consists in certain features of construction, to be hereinafter described, andv the novel features then particularly pointed out in the claims.

In the accompanying drawing is shown a perspective view ofthe apparatus in use.

The frame of the apparatus is made of strips or bars of metal or Wood, which are joined together and fastened at the upturned portion a and the inturned portion or top Z), forming a crook-'shaped end. The inturned ends of the strips or bars are spread apart at c and at their extremities are joined at c' to Vthe sides d of the strips or bars, which are spread apart from the j oined portions a and are continued into handles d'. The sides d are suitablyconnected byt-he tie-bars or rods e.

Mounted in the sides (Z is a windlass f, which at one end is provided with a handcrank g and at the other end with a ratchetwheel 7a.

is a pawl which engages the teeth of the ratchet-wheel, preventing retrograde movement thereof.

Mounted in the sides between the portion co and the points c' is a pulley or sheave lt, over which passes a rope 01' cable Z, which is secured to and is adapted to be wound upon the windlass. Secured to the top portion b is a bail m, in which is swiveled ahook n. The

crooked portion a Z) is provided with a series of perforations 0, which receive the pivot p of the bail m, so that the bail can be adj usted.

The apparatus is intended for use in hoisting objects into a building,'such as ice into an ice-storage house, being designed to dispense with the endless chain usually employed for such purpose. Then the apparatus is out of use, the frame hangs with the handles d' down below the point of support ofthe apparatus.

In operation the hook n is engaged with a suitable elevated support, such as a hanging link at the top of a window-frame, and the apparatus thereby hung in place. desired to raise an object r, (that may indicate a block of ice,) the latter is secured to the rope or cable Z, when the weight of the 0bject will be snflicient to cause the handles to swing upwardly. By reason of the relative positions of the hook n and the pulley lt the upward movement of the handles will continue until the weight on such rope causes the parts to equipoise or counterbalance; but the part of the rope below the pulley 71: will always be to one side of the bail m and its hook in Vertical parallel line therewith. VVhen the handles and windlass are thrown out by the Weight of the load, it is evident that the crank of the windlass may be turned without in any manner being interfered with by the rope or the object being raised, and the handles cl' may then be grasped and held by the operator to steady the apparatus without his having to support the weight thereof,

'as would be necessary were the apparatus not held up by the weight of the load. The swiveled hook n permits the complete revolution of the apparatus, so that it may be more con- Veniently manipulated and the handles brought within ready access. In order that the part of the rope hanging over the pulley h may be on the proper side of the hook n when the weights of the loads to be lifted are varied, (for otherwise the handles might be thrown up against the objects above the apparatus,) the point of connection of the bailm with the frame may be changed by reinoving the pivot of the bail from the latter and one of the holes o and reinserting it in another hole and in the bail.

That I claiin as new is- 1. In a hoistin g apparatus, the combination of a frame having an upturned and inturned portion, a suspension-hook connected with It being said inturned portion 01' top, a windlass and a pulley, said pulley being monnted in said frame below the hook, and a rope or cable secured to and adapted to be wound upon the windlass and passing over the pulley, substantially as and for the pnrpose set forth.

2. In a hoisting apparatus, the combination of a frame provided with handles at one end and having an upturned and inturned portion at the other end, a Suspension-book connected with said inturned portion or top, a windlass and a pulley, said pulley being mounted in saidframe below the hook, and a rope or cable secured to and adapted to be wound upon the windlass and passing over the pulley, snbstantially as and for the purpose set forth.

'3. In a hoisting apparatns, the combination of a frame provided with a crooked portion at one end, the sides of which frame spread from said crooked portion and are extended into handles, a Suspension-book connected with said crook at top, a windlass and a pulley mounted in said frame, said pnl'ley being monnted in said frame below the hook, anda rope or cable secured to and adapted to be wonnd upon the windlass and passing over the pulley, substantially as and forthe purpose set forth.

4. In a hoisting apparatus, the combination of a frame provided with handles, a swiveled hook connected with the frame, a windlass and a pnlley monnted in said frame, said pulley being mounted in said frame below the hook, and a rope or cable secured to and adapted to be wound upon the windlass and passing over the pulley, substantially as and for the purpose set forth.

5. In a hoisting apparatus, the combination of a frame provided with a crooked portion at one end, having at top ahook adj ustably secnred thereto, a windlass and a pulley mounted in said frame, said pulleyfibeingV to form handles, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
